What does it mean when your portable charger is blinking red
Many manufacturers work with different colors. Therefore, it is not always possible to establish what this or that blinking means unambiguously.
Often the power bank blinks red when you connect it to the charging cable. Constant blinking means the device is charging. You may consider you charged the battery if the LED changes color or lights up continuously.
It depends on the power bank capacity, that the charging process can take up to 12 hours – it all depends on your charger. In addition, a flashing red LED may indicate that the power bank is almost empty.
If the power bank continues to flash red even when you think you have charged it, this may indicate a malfunction. In this case, you should contact the manufacturer’s service center.
How to charge a portable charger? Let’s do the charging correctly
Rumors persist that you should first fully discharge batteries and only then fully charge them. In the case of modern batteries, this statement is misleading. In addition, following these tips can even shorten the lifespan of your power bank under some circumstances.
Spend as much time as you need so your power bank is “ful”, regardless of whether the external battery’s capacity is “full” to the maximum or not. Under no circumstances should you charge your power bank each time you charge 100 percent.
If you do not need the power bank for some time, it is optimal to leave its charge at 30 to 70 percent. Depending on the specific model, you can charge the power bank directly from a wall socket or, for example, via USB.
If your power bank doesn’t have its power supply, you can usually still charge it from an electrical outlet. In most cases, power supplies from smartphones or tablets are suitable. However, it is imperative to ensure that the power supply has a 5-volt output. You always may charge an external battery via your computer’s USB port, but the process will take a little longer.
